Abstract

Illustrated in Fig. 1 is a self-adjusting and free-floating plastic seal. The seal automatically self-adjusts, providing for assembly clearance and tolerance build. The seal floats free to provide for a continuous uniform air seal in an air manifold system. Once installed, the air seal is able to withstand the rigorous fragility testing required for new products.

Self-Adjusting, Free-Floating Plastic Air Seal

       Illustrated in Fig. 1 is a self-adjusting and
free-floating plastic seal.  The seal automatically self-adjusts,
providing for assembly clearance and tolerance build.  The seal
floats free to provide for a continuous uniform air seal in an air
manifold system.  Once installed, the air seal is able to withstand
the rigorous fragility testing required for new products.

      Fig. 1 illustrates how the air seal 1 is positioned in an air
manifold 2 by means of three finger-type hooks 3. The hooks 3 snap
over a restraining ring 4 which is part of the air manifold 2.

      Fig. 2 illustrates how the air seal hooks 3 come in contact
with the restraining ring 4 when pushed or moved in a maximum upward
position.

      Fig. 3 illustrates the air seal 1 in a maximum downward
position, and, also, how the air seal 1 is restrained by the
restraining ring 4.

      After reviewing Figs. 2 and 3, a zone of free movement can be
seen which gives the air seal 1 the ability to self-adjust for
assembly clearance and tolerance build-up, assuring a continuous
uniform seal.
